Description

一种具有喉周肌松监测及返流监控的喉罩 技术领域
本发明涉及医疗器械技术领域，具体是一种具有喉周肌松监测及返流监控的喉罩。
 背景技术
喉罩为作为一种声门上通气用具，已经广泛应用于麻醉和急救的气道管理中。但传统的喉罩仍然存在以下问题：
1、不能实时监测有无胃食管返流物进入喉罩罩囊气室内，误吸入气管中。且喉罩自身不能对返流液及时吸引。
    传统的双管喉罩虽设计有一吸引管道，但吸引管道管腔较小，一旦发生胃食管返流，大量的返流液返流至食管入口处时，食管入口的压力剧增，返流液极有可能会沿着食管入口前壁和罩囊头端的缝隙流入罩囊气室内，误吸入气管中。而这些意外事件的发生均在人体咽喉部，不能从体外及时发现，大量返流液一旦进入气管中，就会引起气道痉挛、缺氧窒息等严重并发症，危及患者安全。
2、不能实时监测人体声门及喉周组织运动来判断喉部的肌松深度及麻醉深度情况。
 技术问题
本发明的目的在于提供一种具有喉周肌松监测及返流监控的喉罩，以解决上述背景技术中提出的问题。
